Here is is the "Fuschsia Programming Language Policy" that was here some time ago https://fuchsia.googlesource.com/fuchsia/+/refs/heads/master...

Anyone knows if this project is going to translate into a real world OS deployed on commercially available devices, one day ?

I don't have a source off hand, but I believe it's already been confirmed that Fuchsia is powering Google's Home Hubs.
